One of the methods of spreading culture in production is the study of its morphobiological features. To be establish of the growth and development features of hybrids of asparagus (Asparagus officinalis L.) of Dutch selection in the conditions of the Steppe of Ukraine. Field, biometric, comparative, statistical. In the TOV Agroekspert Trade (Ivankivsky District, Kherson Oblast) was carried out experimental research in the state grants. The hybrids of Dutch breeding Xenolim, Gijnlim, Grolim and Backlim were the subject of research. The experiments were laid in 2017 after black steam class A planting material. They were planted in trenches 15–18 cm deep and 10 cm wide; they were sprinkled on top with a soil layer of 8–10 cm. It was established the spring growth of shoots. It significantly depended on the temperature conditions of the medium and the maturity group of the hybrids. The formation of green asparagus shoots of high quality depends on the characteristics of hybrids. the hybrids Gijnlim, Grolim and Xenolim are classified to be early ripe, and Backlim are classified to be late-ripening in the conditions of the Steppe of Ukraine.
